摘要
提出一种新的T-S模糊故障树分析方法,该方法将模糊逻辑和T-S模糊模型引入到故障树分析中,使故障树具有处理模糊信息的能力.T-S模糊故障树分析中不需要精确了解部件的故障概率,也不需要精确了解故障的机理,从而解决了系统的事件和故障机理的不确定性问题.最后给出了INS/GPS组合导航系统可靠性分析实例.
A new approach of T-S model based fuzzy fault tree is presented. By introducing the fuzzy logic and T-S model, the new fuzzy fault tree analysis is capable of handling the fuzzy information, and dealing with the uncertainty of the event and fault relation without the exact information about the fault probability and failure mechanism. A simulation example of the reliability analysis in INS/GPS navigation system is given for illustration.
